While the focus of Tuttle and colleagues was on the sino-nasal symptoms in AERD, they found that subjects with AERD treated with mepolizumab had decreased AEC without the need for increase of oral glucocorticoids.9 At the time of data collection, subjects had been on mepolizumab for an average of 5.5 months. In contrast, subjects in our studies required oral glucocorticoids months after initiation of mepolizumab. Mepolizumab, a monocolonal antibody against IL-5, has been shown to decrease asthma exacerbations and blood eosinophilia in patients with asthma.8 While IL-5 antagonists are of interest in AERD, data on anti-IL-5 treatment in this group is scarce. To date, only one study has explored the role of mepolizumab in AERD and described improvement of asthma, nasal symptoms and peripheral absolute eosinophil count (AEC) during the first several months of treatment.9 Here we describe 4 patients with AERD who were treated with mepolizumab for severe glucocorticoid-dependent asthma and experienced poor asthma control and elevation of AEC months after treatment. Methods: Subjects at Brigham and Womens Hospital AERD Center and Montefiore Hospital AERD Center who received mepolizumab for at least 2 months were included. The AERD diagnosis was confirmed by aspirin challenge in all patients. This retrospective study was approved by the Partners healthcare and Montefiore Institutional Review Board. Data was extracted from Partners Healthcare and Montefiore electronic medical record (Epic Systems, Verona, Wisconsin). Data reported are means regular deviation. Outcomes: From the 4 topics with AERD, 2 (50%) had been preserved on aspirin for AERD, as the others cannot tolerate aspirin because of unwanted effects. Three (75%) had been female, 3 defined as BLACK (AA) and everything had been obese. The common age group was 46.87.7 years. At baseline, AEC ranged from 800 cells/uL to 2800 cells/uL. Typical peripheral AEC was 1800 cells/uL and everything had poorly managed glucocorticoid-dependent asthma with 2 (50%) needing daily dental corticosteroids and 2 (50%) needing six or even more dental corticosteroid bursts each year ahead of mepolizumab. The common number of life time polypectomies was 2.755 and the common FEV1% ahead of mepolizumab was 6119.7. Mepolizumab was initiated with an dental glucocorticoid burst. To beginning mepolizumab all sufferers weren’t receiving various other biologics Prior. Subject 4 have been on omalizumab that was discontinued 20 a few months ahead of mepolizumab because of the lack of efficiency. All sufferers had been treated with regular mepolizumab medication dosage for asthma at 100 mg subcutaneous every four weeks and originally had a reduction in AEC and didn’t require extra steroids (Desk-1).

Discussion: Our research identifies a subset of AERD sufferers who didn’t have an extended response to mepolizumab despite a short reduction in AEC. in AERD and defined improvement of asthma, sinus symptoms and peripheral overall eosinophil count number (AEC) through the first almost a year of treatment.9 Here we explain 4 patients with AERD who had been treated with mepolizumab for severe glucocorticoid-dependent asthma and experienced poor asthma control and elevation of AEC months after treatment.

Results: Of the 4 subjects with AERD, 2 (50%) were managed on aspirin for AERD, while the others could not tolerate aspirin due to side effects.

Prior to starting mepolizumab all patients were not receiving other biologics. Subject 4 had been on omalizumab which was discontinued 20 months prior to mepolizumab due to the lack of effectiveness. All patients were treated with standard mepolizumab dosage for asthma at 100 mg subcutaneous every 4 weeks and in the beginning had a decrease in AEC and did not require additional steroids (Table-1).
